To all whom it may concern.-

Be it known that I, JOHN DEVONSHIRE ELLIS, ironmaster, a subject of the Queen of Great Britain and Ireland, residing at the Atlas Steel and Iron Works, Sheffield, in the county of York, England, have invented certain new and useful Improvements in and Apparatus for the Manufacture of Iron or Steel Plates with Ribs or Projections thereon, (for which I have applied for a patent in Great Britain on the 4th October, 1886, No. 12,601,) of which the following is a specification.

My invention relates to the manufacture of steel and iron plates with convex or other form of ribs or projections on one side and plain or concave or other form on the opposite side, the said ribs or projections running lengthwise of theplates and being principally applicable for use in the construction of furnaces or fire-boxes or of flues for stean1-boilers, or for other analogous purposes.

According to my invention I prepare ingots, slabs, or blooms, with or without ribs or projections to suit the section to be produced by the'rolls, the said ingots, slabs, or blooms being made of a length corresponding to the width of the finished plate. The ribs or projections may be cast on the ingot for rolling into plates direct, orthe ingots, with or without cast ribs or projections, 'may be reduced in thickness under ahammer or forging-press or by planing or by cogging in rolls. After being so prepared the steel or iron slabs or blooms are rolled in rolls with grooves and collars, as illustrated in the accompanying drawings, Figure l of which is afront View; Fig. 2, a plan with the rolls removed, and Fig. 3 an end view of apparatus for performing this invention.

The collars which are used with the rolls are shown at X X in Figs. 1 and 3. They are applied to each end of one of the rolls and overlap the other of the rolls. I place a horizontal guard,(l O, at each side of the rolls Y, which can be raised or lowered, as required. For the purpose of preventing the plate from either buckling or moving laterally,r'ibs or guides are placed or formed upon the guards O G, which ribs or guides correspond in shape and size to the hollows rolled in the plate. Thus,whe'n the guards are brought down to the plate during the process of rolling, the ribs of the guard .by fitting the hollows in the plate, prevent the lateral movement of the plate. The gearing for raising or lowering these guards may be worked by hand, steam, or hydraulic power.

As illustrated in the drawings, the'guards G are each guidedin grooves in the roll-framing, and are carried by uprights 13, passing through guiding-brackets b on the roll'fraining, and provided at their upper ends with screws on which work internally-screwed wheels Z, formed with worm-teeth on their peripheries, with which engage worms on the shafts A,

mounted on brackets and worked by handwheels a, as shown;-

I claim 1. In an apparatus for producing steel or iron plates with ribs or projections thereon, the

combination of the rolls and the collars on the ends of one of said rolls and overlapping the other roll, substantially as described.

2. The combination, with rolls for rolling steel or iron plates, as described, of a ribbed guard at each side of the rolls in the manner described, to prevent the buckling or lateral movement of the plates being rolled, substantially as-described and illustrated.

3. The combination, with the rolls for rolling steel or iron plates, of the guards at each side of the rolls, said guards being provided with ribs for the purpose stated, and mechanism,as indicated, for raising and lowering said guards, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN DEVONSHIRE ELLIS.-
